There's too much dead space around the aircraft, you need to crop it tighter. The quality isn't great either. The fence line on the landing gear may bring a motive rejection. I would be surprised if this one got through screening.

Hey thanks a lot for your help. Ι must clean my sensor
Should I leave the sharpness as it is? I am not a big fan of oversharpenning but all the rejections so far where for soft and I guess I am oversharpenning now
